Anyways, water only fasting every other day is working for me so I <br>
thought I would share<br></blockquote></div><br><div>### I never got fat in my life but over the years there was some creeping up of my weight. About two years ago I started intermittent fasting and now I am only 2 lb above my high school/college weight. I am definitely a fan of this habit.</div><div><br></div><div>I found that fasting for 36 hours was rather taxing, I would cheat and end up eating lots of snacks before the "official" end of the fast. Now I eat one meal a day on weekdays, and this happens to be a breakfast, with absolutely no snacks in between. I find it is quite easy, I don't have to exert much self-control to keep it going. On weekends I pig out, eating huge ribeyes smothered in butter and blue cheese. Of course, the quality of your one meal of the day is still very important - it should have low glycemic index, low average caloric density, be high in nutrients including animal protein and fat. I am finding that a very large green salad (arugula, kale, spinach) with fresh tomatoes, avocado and various combinations of sardines, other meats, aged cheeses, nuts, olive oil, balsamic vinegar, fresh herbs, berries and other goodies (about 800 - 900 calories) followed by a Panera pastry keep me satisfied until the next breakfast.</div><div><br></div><div>Regarding the role of autophagy - this is indeed a crucial maintenance process which becomes suppressed by the continuous ad lib feeding typical of modern lifestyles. Humans have not evolved under conditions of continuous food availability and our metabolism is not adapted to it. However, I doubt that recycling of proteins is really what matters in autophagy - my guess is that the real mechanism responsible for aging retardation by fasting is actually mitophagy, or the disposal of mitochondria. This process selectively removes metabolically defective mitochondria and their mutated genomes that are responsible for metabolic defects, thus slowing down the long-term accumulation of mitochondrial mutations, which is one of the key mediators of aging.</div></div>
